YOU MUST PROVIDE SAMPLES OF THE TYPES OF GRAPHS YOUR APP WILL DO
I have files on my server and I want to be able to generate graphs from them. Scripts generate new files and then I want to graph them. The program should allow the user to choose a file and then create a graph. The graphs should be nice and should allow for the user to visualize different variables and multiple views. Please send me examples of the type of graphs you can generate with your program.
Also, the following functionality would be needed:
1. have an interactive chart so that when an area is clicked on it reads from a database and based on the area that was clicked it shows some additional information? I would like to click on a "peak" in the graph and there then to be a call to a data base (I guess using XMLHttpRequest ) to look up that date and say 2 dates ahead and before that date and show certain fields for those records.
2. Trend lines (linear, perhaps quadratic (and higher powers), perhaps exponential, etc). See attached graphs for sample.
3. There should be some interface on the graph which will allow the user to put in a date range and download just the data from that date range. I mean by this suppose that the x axis is time and suppose there is a peak in the graph say between May 1 and June 17. Can you arrange it so that I can input a date range (like May 1 to June 17) and save that data to a separate file (so that I can do further analysis on just that data).
The server is Windows 2008. PHP, Mysql, perl are installed on the computer
